Best subwoofer for 1000 to 2000 dollars

Hi, I'm using these Condor mini monitor speakers. They use a 7 inch Scanspeak midbase and a Scanspeak tweeter. I'm looking to get a sub for music and home theather. The Subs I'm looking at, are Velodyne HGS 12, HGS 15, Earthquake SuperNova, which uses a 12 inch woofer and a passive 12 inch woofer, Tyler Acoustics Taylo Ref Sub, which uses a 12 inch woofer, Infinity IL 120S w/ rabos kit - or the more expensive Infinity sub with rabos kit, ITM1.2SC, and the JM Lab SW 900. If anyone has any other recommendations, please say them.
